In a storage system allowing redundant writing, a technology is provided capable of achieving control including efficient return to redundancy while reducing load on a host and trouble for a user. A polysilicon layer for a floating gate has a stack structure of a doped polysilicon layer and an undoped polysilicon layer, whereby the polysilicon layer is prevented from being oxidized at the interface of the polysilicon layer and a dielectric layer in the process of forming the dielectric layer or in other subsequent process. Protocol information in received PAR PTSEs is then supplied to a protocol device associated with the PAR-enabled device. A similar system is provided for the passenger side airbag module. Further described is the use of the aforementioned antibodies, antigens, polynucleotides and vectors in adoptive immunotherapy, preferably for the treatment or prevention of HCV infection during liver transplantation.
